Man in custody found unresponsive, dies

A 44-year-old man died Saturday afternoon while in police custody on the West Side, officials said.

John Hubbard had been arrested on Saturday and was taken to a police building on the 3300 block of West Fillmore Street in the Homan Square neighborhood, said Chicago Police News Affairs Officer Daniel O’Brien.

Officers later found Hubbard, of the 3500 block of South Rhodes Avenue in the Bronzeville neighborhood, unresponsive inside an interview room, O’Brien said.

Hubbard was taken to Mt. Sinai Hospital, where he was pronounced dead at 1:25 p.m., the Cook County medical examiner’s office said.

After a toxicology exam, the medical examiner's office determined that Hubbard died of heroin intoxication and his death was ruled an accident, according to Frank Shuftan, a spokesman for the Cook County medical examiner's office.

It was not immediately clear where the man had been arrested or for what offense.
